waking up in the night an early preganncy symptom? please help!!

So I'm not sure if I'm pregnant yet as way to early to test. Just some info we used the withdrawal method, and it's been 5 or so days after I would of conceived if I am pregnant. I never get sore breasts before periods or anything but I've got the tiniest bit of boob pain like I never have it so I'm like hmmmm, when I had sex I was 5 days late for my period and I still haven't got it. Now I'm waking up in the night. And it isn't as easy for me to go to sleep and usually I would fall asleep so quickly. I would be very kind of hot too. Did any one have this as an early pregnancy symptom or know anything else? Please help!!!
